Over 20 Republican congressmen sent a letter to President Donald Trump, urging US troops not to be withdrawn from Germany, CNN reported.

It is expected that 9,500 US troops will be withdrawn from Germany. An official order to begin the movement of troops has not yet been given but is expected in the near future.

Nearly 34,000 US troops are currently deployed in Germany.

"We strongly believe that NATO allies, such as Germany, should do more to contribute to our joint defense efforts. At the same time, we also know that the forward stationing of American troops since the end of World War II has helped to prevent another world war and, most importantly, has helped make America safer," the lawmakers wrote.

"In Europe, the threats posed by Russia have not lessened, and we believe that signs of a weakened US commitment to NATO will encourage further Russian aggression and opportunism. In addition, the overall limit on troops would prevent us from conducting the exercises that are necessary for the training and readiness of our forces and those of our allies," they added. 

"The troop limit would also significantly reduce the number of US forces that can flow through Germany for deployment to bases around the world, causing serious logistical challenges," the letter reads.
